FnFX enables owners of Toshiba laptops to change the LCD brightness,
control, the internal fan and use the special keys on their keyboard
(Fn-x combinations, hot-keys). The internal functions will give the
possibility to map the Fn-Keys to functions like volume up/down, mute,
suspend to disk, suspend to ram and switch LCD/CRT/TV-out. These
functions heavily depend on the system and/or kernel configuration.
You will need at least a kernel (v2.4.x, v2.5.x, v2.6.x) with ACPI and
Toshiba support (CONFIG_ACPI and CONFIG_ACPI_TOSHIBA).
